bug: jest defaults are overriding passed args.

• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Stencil Version

12.15.0

Current Behavior

Command line flags passed to stencil test are being overridden by the stencil defaults.

Running stencil test --spec --passWithNoTests will log out the correct arguments:

[35:48.6]  @stencil/core
[35:48.8]  v2.15.0 ⛷
[35:48.9]  testing spec files
[35:48.9]  jest args: --passWithNoTests --spec --max-workers=8

But then fail with:

No tests found, exiting with code 1
Run with `--passWithNoTests` to exit with code 0

You can see the override happening on line:

And if we add some logs, we can see the passed flag being overridden:

Expected Behavior

Defaults should be the default, and not override the passed flags

Steps to Reproduce

In a stencil repo with no tests, run stencil test --spec --passWithNoTests and observe failure.

The fix for this issue has been released as a part of Stencil v2.15.1. As a result I'm going to close this issue. Thanks again for your help with this!
